Why are 12v Cummins so good?
A stroke of 4.72 inches (accompanied by a 4.02-inch bore) yields 359 cubic inches, incredible low-rpm torque and remarkable fuel efficiency. Along with it being in an inline engine’s nature to produce gobs of torque, they’re also easier to work on than the V8 competition.
How many miles is a 12v Cummins good for?
Barring abuse (dirty air, dirty oil, lack of water, corrosion, etc), your engine should be good for at least 500,000 miles. I have seen many with over 300,000 some over 400K and a few over 600K.
Is Cummins better than PowerStroke?
The Power Stroke has more horsepower, but slightly less torque, while the Cummins has the opposite. However, as noted by AutoWise, the Power Stroke ultimately produces more horsepower, which is a better indicator of engine strength in real driving situations.
What’s better 12v or 24v Cummins?
When it comes to serious power and performance the 12v 5.9 Cummins takes the win. These engines are known to hold up better at extreme power levels when compared to the 24v engines. P7100 injection pumps on the 6BT are easier to mod and support the extra power.
How much fuel pressure should a 2001 Cummins have?
12-15 PSI Is Ideal To keep the notorious chain reaction event of a failed lift pump from starving (and then killing) the VP44, 5 psi of supply pressure is the minimum you should see during idle, driving and/or wide-open throttle. Whenever possible, 12 to 15 psi worth of fuel pressure should be your goal.
Is the 24 valve a good engine?
Outside of the fuel system, the 5.9 24v is a very reliable engine. The engine internals such as the pistons, rod, and crankshaft will last a lifetime and can hold up beyond 500,000 miles.
What kind of fuel injection does a Cummins 5.9 have?
In order to have a reliable fuel injection system, the Cummins 5.9 comes from the factory with an OEM lift pump. However, 1998 to 2004 model year 24v’s experience common lift pump failure. These early year 24v’s had their lift pumps attached to the engine block.
What kind of pump do I need for a Cummins 12 valve?
We offer complete factory replacement P7100 injection pumps or performance pumps from BD and Industrial Injection. Dynomite Diesel, BD, and Industrial Injection also supply us with an assortment of performance injectors and unique fuel plates for an extremely simple power adder.
What are the symptoms of a Cummins 5.9 engine problem?
Cummins 5.9 Faulty Fuel Injector Symptoms 1 Hard start or no start 2 Cylinder misfires 3 Fuel in the engine oil 4 Poor idling and performance, surging, etc.
When did the Cummins 5.9L B series come out?
The Cummins 5.9L “B-Series” diesel engine was produced from 1984 up until 2007. First generation versions were named the 6BT but also commonly referred to as the 12v, or 12-valve. Each cylinder had 2 valves, hence the name 12-valve. Midway through 1998, the 6BT was replaced with the ISB, which stands for “Interact System B”.
